Description

Data processing method and device

Technical field

Background technique

In the dual connectivity technology, in order to better perform load balancing between base stations and maximize cell resources, a split data radio bearer is introduced. In other words, in the dual connectivity technology, there are split data radio bearers and non-segment data radio bearers. The non-data split radio bearers may exist only in the primary base station MeNB or the secondary base station SeNB. There are three types of data radio bearers, and only exist. The data radio bearer on the MeNB is referred to as the MeNB bearer. The data radio bearer existing only on the SeNB is referred to as the SeNB bearer, and the data radio bearers existing on the MeNB and the SeNB are referred to as the split split bearer.

In the user plane protocol architecture shown in FIG. 1, when the Bear split is configured, the data of the MeNB is split at the Packet Data Convergence Protocol (PDCP) layer. Since the MeNB and the SeNB have independent RLC entities, once the data packet is sent by the PDCP entity to the RLC entity located in the MeNB or the SeNB, the subsequent data transmission can only be completed in the MeNB or the SeNB.

With the rapid growth of data services, the licensed spectrum will not be able to withstand such a huge amount of data in the near future; therefore, LTE operators consider deploying LTE in unlicensed carriers and sharing licensed carriers through unlicensed spectrum. Data traffic in . In some cases, unlicensed carriers need to compete to be used. In the user plane protocol architecture shown in FIG. 1 , the current PDCP entity does not automatically request the retransmission function, and cannot perform the retransmission operation in time. Thus, when a link has a problem, it is difficult to perform a packet retransmission operation in time.

Embodiments of the invention

In the embodiment of the present invention, it is determined whether a resource competition failure occurs in a data transmission process, where the data transmission process is a data transmission process including a traffic offloading; and when a resource competition fails in the data transmission process, determining the data transmission process A packet that was not successfully transmitted.

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Embodiment 1

2 is a schematic flowchart 1 of an implementation process of a data processing method according to an embodiment of the present invention. As shown in FIG. 2, a data processing method according to an embodiment of the present invention includes:

Step 201: Determine whether a resource competition failure occurs in the data transmission process, where the data transmission process is a data transmission process including a offloaded bearer;

Here, the PDCP of the transmitting end determines whether a resource competition failure occurs in the data transmission process, and may be implicit or explicit.

In an example, the PDCP of the transmitting end determines whether a resource contention failure occurs during data transmission by implicitly: determining whether a feedback message of the data transmission is received while waiting for a preset time period; and not receiving the preset time period while waiting The feedback message of the data transmission is that the resource competition failure occurs during the data transmission. The feedback message of the data transmission includes an acknowledgement indication (ACK) and a non-acknowledgement indication (NACK) fed back by the protocol data unit PDU to the sender PDCP. That is to say, when the PDCP of the transmitting end does not receive the acknowledgment indication (ACK) of the corresponding PDU sent by the receiving end, the non-acknowledgement indication (NACK) of the corresponding PDU is not received, that is, the acknowledgment indication (ACK) and non-confirmation of the corresponding PDU. When the indication (NACK) is not received, it is considered to be caused by the failure of resource competition. Correspondingly, the transmitting end PDCP receives the non-acknowledgement indication (NACK) of the corresponding PDU sent by the receiving end, which is considered to be caused by the insufficient wireless environment.

In yet another example, the PDCP of the transmitting end determines whether a resource contention failure occurs during data transmission by explicitly determining:

In the first manner, it is determined whether the notification message of the resource competition failure is received; when the notification message of the resource competition failure is received, the resource competition failure occurs in the data transmission process. Here, the pass The known message includes a state in which the unlicensed carrier performs resource competition (which may be performed by the terminal or performed by the base station of the unlicensed carrier), for example, the contention of the competition resource, the information competing for the resource includes the frequency domain resource, and the time domain resource; or the resource Competition failure information. The end of the contention process can be sent to the base station of the authorized carrier, and/or the terminal. The base station transmits through the X2 port, and the terminal and the base station transmit through the air interface.

In the second method, it is determined whether the notification message of the resource competition failure is received, and the notification message of the resource competition failure carries the identifier of the unsuccessfully transmitted data packet; when the notification message of the resource competition failure is received, the data transmission process is obtained. A resource competition has failed. Here, the notification message includes packet information that cannot be retransmitted due to resource competition failure, such as a packet sequence number SN, etc., may be a new message, or an indication is added in the status report to distinguish whether the wireless environment is not good, or Resources are not competing. It is more appropriate to use the trigger method to send a notification message when the first packet cannot be sent, or to send a notification message when the first packet is sent for a specified period of time, or after the resource fails. Send a notification message.

Manner 3: determining whether a notification message of successful resource competition is received; when receiving the notification message that the resource competition is successful, determining the current resource usage according to the content of the message in the notification message.

It should be noted that the notification message is sent when the first data packet cannot be sent; or the notification message is sent when the first data packet cannot be sent for a specified time and cannot be sent; or, the notification message Sent after the resource competition process ends.

Step 202: When a resource competition failure occurs in the data transmission process, determining a data packet that is not successfully transmitted during the data transmission process.

Here, when there is a resource competition failure in the data transmission process, the PDCP of the transmitting end determines whether there is a resource competition failure in the data transmission process. The following two methods may be used to determine the data packet that is not successfully transmitted in the data transmission process. The way:

Mode A: When the PDCP of the transmitting end determines that the resource competition fails during the data transmission in an implicit or explicit manner, the PDCP of the transmitting end determines that the PDCP of the transmitting end cannot directly learn the data packet that is not successfully transmitted. The data packet that is not successfully transmitted during the data transmission process includes: searching for a current data packet state; and when there is a data packet in the data packet state that does not receive the feedback information, determining that the data packet is the data transmission A packet that was not successfully transmitted during the process.

Mode B: When the PDCP of the transmitting end determines that the resource competition fails in the data transmission process by using the explicit mode 2, the notification message of the resource competition failure carries the identifier of the unsuccessfully transmitted data packet, so The PDCP of the terminal determines the data packet that is not successfully transmitted during the data transmission, and includes: parsing the notification message that the resource competition fails, and obtaining the identifier of the data packet that is not successfully transmitted; and identifying the data packet corresponding to the unsuccessfully transmitted data packet It is determined that the data packet was not successfully transmitted during the data transmission.

The data processing method in the embodiment of the present invention determines whether a resource competition failure occurs in the data transmission process, where the data transmission process is a data transmission process including a offloaded bearer; and the resource competition fails in the data transmission process, A packet that is not successfully transmitted during the data transmission is determined. In this way, the sender can know the reason why the data cannot be sent in time. For the case that needs to be processed in time, the retransmission can be arranged through a reliable path, thereby improving the user experience.

The embodiment of the present invention further provides a computer storage medium, where the computer storage medium stores computer executable instructions, and the computer executable instructions are used to execute the data processing method according to the embodiment of the present invention.

Embodiment 2

FIG. 3 is a schematic flowchart of the implementation of the data processing method according to the embodiment of the present invention. As shown in FIG. 3, the data processing method in the embodiment of the present invention includes:

Here, the PDCP of the transmitting end determines whether the resource competition failure occurs in the data transmission process, and may be implicit or displayed.

In an example, the PDCP of the transmitting end determines whether a resource contention failure occurs during data transmission by implicitly: determining whether a feedback message of the data transmission is received while waiting for a preset time period; and not receiving the preset time period while waiting The feedback message of the data transmission is that the resource competition failure occurs during the data transmission. The feedback message of the data transmission includes an acknowledgement indication (ACK) and a non-acknowledgement indication (NACK) fed back by the protocol data unit PDU to the sender PDCP. That is to say, when the PDCP of the transmitting end does not receive the acknowledgment indication (ACK) of the corresponding PDU sent by the receiving end, nor does it receive the non-acknowledgement indication (NACK) of the corresponding PDU, that is, the acknowledgment indication (ACK) of the corresponding PDU. When neither the non-acknowledgement indication (NACK) is received, it is considered to be caused by the failure of resource competition. Correspondingly, the transmitting end PDCP receives the non-acknowledgement indication (NACK) of the corresponding PDU sent by the receiving end, which is considered to be caused by the insufficient wireless environment.

In the first manner, it is determined whether the notification message of the resource competition failure is received; when the notification message of the resource competition failure is received, the resource competition failure occurs in the data transmission process. Here, the notification message includes a state in which the unlicensed carrier performs resource competition (which may be performed by the terminal or performed by the base station of the unlicensed carrier), for example, contention of the competition resource, the information competing to the resource includes the frequency domain resource, and the time domain. Resource; or resource competition failure information. The end of the contention process can be sent to the base station of the authorized carrier, and/or the terminal. The base station transmits through the X2 port, and the terminal and the base station transmit through the air interface.

Step 202: When a resource competition failure occurs in the data transmission process, determining a data packet that is not successfully transmitted during the data transmission process;

Here, when there is a resource competition failure in the data transmission process, the PDCP of the transmitting end may determine whether there is a resource competition failure in the data transmission process. How to determine the data packets that were not successfully transmitted during the data transmission:

Steps 301-302: determining, according to the load condition of the current authorized carrier, that the data packet that is not successfully transmitted in the data transmission process is sent by the authorized carrier; and instructing to cancel sending the unsuccessfully transmitted data packet by using the unlicensed carrier.

Here, when it is determined that the data packet that is not successfully transmitted in the data transmission process is P-2 data, the PDCP of the transmitting end decides to send the data of the P-2 through the authorized carrier according to the load condition of the current authorized carrier, and indicates the auxiliary The base station SeNB cancels transmitting the data of the unsuccessfully transmitted data packet P-2 through the unlicensed carrier.

According to the data processing method of the embodiment of the present invention, on the basis of determining the data packet that is not successfully transmitted in the data transmission process, determining, according to the load condition of the current authorized carrier, the data packet that is not successfully transmitted during the data transmission process. Sent by the authorized carrier; indicating cancellation of the unsuccessfully transmitted data packet by the unlicensed carrier. In this way, the sender can know the reason why the data cannot be sent in time. For the case that needs to be processed in time, the retransmission can be arranged through a reliable path, thereby improving the user experience.

Here, the foregoing storage medium may include, but not limited to, a U disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a mobile hard disk, a magnetic disk, or an optical disk. A medium that can store program code.

The data processing method according to the embodiment of the present invention is described in detail below in conjunction with a specific application scenario and an application example thereof.

Application scenario: As shown in FIG. 4, a macro base station and an unlicensed carrier node are deployed in the network, and the two base stations form an access network of the system architecture of the embodiment of the present invention. In this embodiment, the MeNB and the SeNB are respectively used as the master control node. Describe with the offload node, and the terminal performs dual connectivity configuration.

Based on the network architecture shown in FIG. 4, the data processing methods corresponding to the following application examples are respectively explained.

Application example one

In the downlink data transmission, the MeNB performs the offloading decision on the downlink data, and sends part of the data to the SeNB, and the remaining data is directly sent to the terminal. After the SeNB reprocesses the received offloaded data, the offloaded data is transmitted through the split link. The UE receives the data packet received by the MeNB on the wireless link with each access node, and performs joint processing on the same.

For example, the MeNB performs shunting decisions for PDCP PDUs (SN numbers P-2, P-3, P-4, P-5, P-6, P-7), where P-2, P-3, P -4, P-5 is transmitted by the SeNB, and P-6, P-7 are transmitted by the MeNB. Therefore, the RLC layer of the SeNB will receive the PDCP PDU (the SN numbers are P-2, P-3, P-4, P-). 5) The RLC layer of the MeNB will receive the PDCP PDU (SN number is P-6, P-7).

The RLC layer further processes the data packets. The RLC layer of the SeNB performs PDCP PDUs (SN numbers P-2, P-3, P-4, and P-5), and performs segmentation concatenation according to the indication of the MAC layer. The PDUs forming the RLC are as shown in Table 1 below:

Table I

The RLC layer of the MeNB, the PDCP PDUs (SN numbers are P-6, P-7) are segmentally concatenated according to the indication of the MAC layer to form RLC PDUs, as shown in Table 2 below, because the RLC is independent of the eNB. Therefore, the SN of the RLC is numbered separately from the two base stations, and may be the same. In this embodiment, the number is changed to be different. The data packets of the MeNB are processed according to the current technology and will not be described in detail.

Table II

The following describes the process of transmitting data packets on the SeNB. Resource competition is performed by the SeNB:

At the time of T1, the first time the contention resource is successful, the resources on the SeNB are contending, and the data can be transmitted. The RLC of the SeNB receives the ACK information of the R-4 and R-5 sent by the terminal, notifies the PDCP of the MeNB, and the PDCP of the MeNB learns the P. -3, P-4 and P-5 packets have been received. The RLC of the SeNB receives the NACK information of R-3 and R-6, and learns that it is caused by the wireless environment and is processed according to the current mechanism.

The RLC layer of the terminal receives the data R-4, R-5 on the SeNB.

At time T2, the second time the contention resource fails, and the data cannot be sent. At this time, the RLC of the SeNB does not receive the ACK information of R-3 and R-6, and does not receive the NACK information of R-3 and R-6. Due to the failure of resource competition, the PDCP layer of the MeNB is notified, and the data of the P-2 is not successfully transmitted, because the resource competition fails. The MeNB decides according to the load of the currently authorized carrier, and the like. The data of P-2 is sent through the authorized carrier, and the RLC of the SeNB is notified, and the data of P-2 is canceled.

or,

At time T2, the second time the contention resource fails, and the data cannot be sent. At this time, the SeNB informs the PDCP layer of the MeNB through the notification message (through the X2 port) through the notification message (via the X2 port), and the PDCP layer of the MeNB according to the current packet status (P -3, P-4 and P-5 packets have been received), knowing that P-2 failed to send. The MeNB decides to transmit the data of the P-2 through the authorized carrier according to the load of the current authorized carrier, and the like, and notifies the RLC of the SeNB by the notification message, and the data of the P-2 is canceled.

or,

At the time of T2, the second time the contention resource fails, and the data cannot be sent. At this time, the SeNB informs the PDCP layer of the MeNB through the notification message that the PDCP data packet P-2 fails to transmit information, and the PDCP layer of the MeNB is based on the load of the current authorized carrier. It is decided to transmit the data of P-2 through the authorized carrier, and notify the RLC of the SeNB by the notification message, and the data of P-2 is canceled.

Of course, the above application example is to send a notification message after the failure of the secondary contention resource. In an actual application, the SeNB may notify the PDCP layer of the MeNB after the specified number of times of resource competition fails.

Application example two

In the uplink data transmission, the PDCP of the UE performs the offloading decision on the uplink data, and sends part of the data to the SeNB, and the remaining data is directly sent to the MeNB;

After the offloaded data sent to the SeNB is reprocessed, the offloaded data is transmitted to the SeNB through the offload link;

The MeNB receives the data packet received by the UE on the radio link with each access node, and performs joint processing on the same.

For example, the UE performs shunting decisions for PDCP PDUs (SN numbers P-2, P-3, P-4, P-5, P-6, P-7), where P-2, P-3, P-4 P-5 is sent by the SeNB, and P-6 and P-7 are sent by the MeNB. Therefore, the RLC layer of the SeNB on the UE will receive the PDCP PDU (the SN numbers are P-2, P-3, P-4, P-). 5) The RLC layer of the MeNB on the UE will receive the PDCP PDU (the SN number is P-6, P-7).

The RLC layer processes the data packets again. The RLC layer of the SeNB on the UE sets the PDCP PDUs (SN numbers P-2, P-3, P-4, and P-5) according to the MAC layer indication. The PDUs forming the RLC are as shown in Table 1 in the foregoing application example 1.

The RLC layer of the MeNB on the UE, the PDCP PDUs (the SN number is P-6, P-7) are segmentally cascaded according to the indication of the MAC layer to form the RLC PDU, as shown in Table 2 in the foregoing application example 1. Since the RLC is independent of the eNB, the SN of the RLC is numbered separately from the two base stations, and may be the same. This embodiment is changed to a different number for the sake of distinction. The data packets sent by the UE to the MeNB are processed according to the current technology, and will not be described in detail.

The following describes the process of transmitting a data packet to the SeNB on the UE, and the resource competition is performed by the UE:

At the time of T1, the first time the contention resource is successful, and the resource on the SeNB can be used to transmit data. The RLC of the SeNB on the UE receives the R-4 and R-5 ACK information sent by the terminal, and notifies the UE of the PDCP of the MeNB. The PDCP of the upper MeNB learns that P-3, P-4 and P-5 packets have been received. The RLC of the SeNB on the UE receives the NACK information of R-3 and R-6, and it is learned that it is caused by the wireless environment and is processed according to the current mechanism.

The RLC layer of the SeNB receives the data R-4, R-5 sent to the SeNB.

At the time of T2, the second time the contention resource fails, and the data cannot be sent. At this time (the resource competition process ends, or after waiting for the specified time, the UE still cannot compete for the resource), the UE informs the UE of the information that the resource competition fails by the notification message. The PDCP layer of the MeNB, the PDCP layer of the MeNB on the UE knows that the P-2 transmission fails according to the current packet status (P-3, P-4 and P-5 packets have been received). The PDCP layer of the UE decides to send the data of the P-2 through the authorized carrier according to the load of the current authorized carrier, and the like, and notifies the RLC of the SeNB on the UE by the notification message, and the data of the P-2 is canceled.

or,

At time T2, the second time the contention resource fails, and the data cannot be sent. At this time, the UE sends the information that the PDCP data packet P-2 fails to be sent through the notification message (which may be a new message or an indication in the status report, due to the resource. The PDCP layer of the MeNB is notified to the UE. The PDCP layer of the MeNB on the UE decides to transmit the data of the P-2 through the authorized carrier according to the load of the current authorized carrier, and the RLC of the SeNB is notified by the notification message. , P-2 data Cancel sending.

If a packet such as P-10 is also caused by a resource competition failure, the notification message is sent again, carrying the SN number of the P-10, or the resource competition failure information.

The sending end receives the notification message that the data cannot be sent due to the failure of the resource competition, and performs processing in time, and may not affect the subsequent newly transmitted data, that is, the data that needs to be sent later, or the data may be shunted according to a predetermined rule.
